CAUTION
The concept of frame mounted type Crack Saws has been successfully utilized for many years as a practical solution to many types of random crack sawing requirements. The basic concept is proven and well accepted within the associated marketplaces. Use of a Crack Saw requires strenuous work activity. This type of work activity can be considered to be greater in magnitude than that experienced with the use of many other types of both light construction and lawn and garden related equipment. This type of work activity should only be attempted by operators of adequate physical size and stature, mental awareness and physical strength and condition. The body parts most noticeably affected during the planing process are the arms, hands, wrists, shoulders, lower back and legs. The process can also produce excessive stress/strain directly to the back muscles, spinal vertebrae and many other body parts. Back related pain can be a side effect of utilizing a Crack Saw. An operator with a chronic back related problem or a history of back and/or other medically related problems should not attempt to utilize the Crack Saw. Use of the Crack Saw may only aggravate this and any other medically related problem. Because of the diverse type of prevailing job applications, job site conditions, operator experience levels and operator physical characteristics, no warranty, guarantee, representation and/or liability is made by the manufacturer as to the absolute correctness or sufficiency of any operational procedure, operational position and/or technique. There is no absolute guarantee that an operator of any given experience level, physical size and/or physical condition will be immune to the possibility of and/or probable physical side effects of the normal use of the Crack Saw. Each potential operator must be made aware of and assume the operational and physical liability described and/or associated with the use of the Crack Saw. Improper use of the Crack Saw can result in property damage and/or personal injury, including death. Each potential operator not willing to assume the operational and physical liability described and/or associated with the use of the Crack Saw, should not operate it. Proper levels of operator experience, skill and common sense are essential for maximizing the safe and efficient operation of the Crack Saw.

RCC130H-CRACK SAW OPERATION AND PARTS MANUAL REV #1 (11/18/04) PAGE 10
SAFETY PRECAUTIONS
6) Prolonged use of the CRACK SAW (or other, similar machines) exposes the operator to vibrations which may produce Whitefinger Disease (Raynaud's Phenomenon). This phenomenon reduces the hand's ability to feel and regulate temperature, produces numbness and burning sensations and may cause nerve and circulation damage and tissue necrosis. Antivibration systems do not guarantee that you will not sustain Whitefinger Disease. Therefore, continuous and regular users should closely monitor the condition of their hands and fingers. After each period of use, exercise to restore normal blood circulation. If any of the symptoms appear, seek medical advice immediately.
7) Clothing must be sturdy and snug fitting, but allow complete freedom of movement. Never wear loose fitting jackets, scarves, neckties, jewelry, flared or cuffed pants or anything that could become caught on controls or moving parts. Wear long pants to protect your legs. Protect your hands with heavy duty, nonslip gloves to improve your grip. Good footing is most important when operating the CRACK SAW. Wear sturdy boots with nonslip soles. Steel-toed safety shoes are highly recommended. Keep shoes properly laced. Never wear tennis shoes or other, similar type shoes which afford little or no protection. Wear an approved safety hard hat to protect the operator'(s') head(s) where there is a danger of head injuries. Noise, generated by the operation of the CRACK SAW and the actual process itself, can damage your hearing. Wear approved sound barriers (ear plugs or ear mufflers) to protect your hearing. Continuous and regular operators should have their hearing checked regularly.
8) Visually inspect the Crack Saw, components, tools and accessories for damaged or worn parts. BEFORE each use:
a) Disconnect the engine spark plug wire or power source cable.

Before Starting the Engine
FILLING THE ENGINE CRANKCASE WITH OIL.
Note: The RCC130H Crack Saw is shipped with oil in the engine crankcase. Fuel is drained from the fuel tank and will be marked accordingly by factory personnel.
Tools Required: 1 each, small, clean funnel.
The RCC130H Series Crack Saw comes equipped with a Honda 13 HP gasoline engine. The engine is not normally pre-serviced at the factory (see note above) and will require the addition of oil in the crankcase before being placed in service. Consult the material supplied by the engine manufacturer for the engine that has been ordered with your Crack Saw. Carefully review this material to become familiar with specific operating characteristics, recommendations and service requirements.
1) Determine the location(s) of both the oil filler and oil drain plug(s).
2) Wipe oil, dust and accumulated dirt from the filler plug area.
3) Using the funnel, fill the engine crankcase with a high grade motor oil. Consult the material supplied by the engine manufacturer for proper amount, weight and service classification.
4) Replace the oil filler plug and tighten. Wipe off any excess oil spilled on the engine crankcase and Crack Saw.
5) Do not operate the engine unless proper oil level is maintained as per the material supplied by the engine manufacturer.
FILLING THE RCC130H FUEL TANK.
Tools Required: 1 each, small, clean funnel.
CAUTION
Never mix oil with gasoline. Four cycle engines are not designed to be operated with oil mixed with the gasoline.
RCC130H-CRACK SAW OPERATION AND PARTS MANUAL REV #1 (11/18/04) PAGE 14
ASSEMBLY INSTRUCTIONS/OPERATIONS
1) Determine the location of the fuel tank filler cap.
2) Carefully clean the filler cap and surrounding area to insure that no dirt or debris falls into the fuel tank. Remove the filler cap.
3) Using the funnel, fill the fuel tank with fresh, clean fuel according to the specifications outlined in the material supplied by the engine manufacturer. Do not overfill the tank or spill any fuel. If the fuel tank incorporates a screen mesh to prevent debris from falling into the tank, do not remove to increase the fill rate. Replace the filler cap. Wipe away any excess spilled fuel.
DANGER
MANY FUELS ARE EXTREMELY FLAMMABLE. DO NOT SMOKE NEAR THE FUEL TANK. DO NOT FILL THE FUEL TANK WITH THE ENGINE RUNNING OR IF IT IS HOT. ALLOW AMPLE TIME BETWEEN EACH REFUELING FOR THE ENGINE TO COOL.
Operation
THEORY OF OPERATION.
The RCC130H Crack Saw operates on the principle of transmitting horsepower through a V-Belt transmission directly to an industry standard, 8 inch diameter, diamond segment blade of various widths.
The crack sawing process is directly controlled by these conditions:
a) The use of a suitable mechanism (diamond blade) of proper design and configuration to penetrate the work surface and remove material while delivering acceptable service life.
b) Sufficient static weight supporting the diamond blade to allow it to effectively penetrate the work surface and remove material.
c) Adequate horsepower capable of rotating the diamond blade at industry recognized speeds against the work surface to deliver acceptable productivity rates.
Since no two materials are exactly alike, no two work surface materials can be sawed by the exact same method. The nature of the sawing process, along with operator experience, skill and common sense, would suggest that efficient and productive crack sawing is a matter of trial and error. Combinations of diamond blade type, condition, and
feed rate are direct factors that will also determine the overall success of the job application.
INFORMATION RELATIVE TO THE USE OF DIAMOND BLADES.
Safety requirements always override performance considerations. Diamond blade technology has made such rapid advances during the past few years that a diamond blade, properly used, on well designed and well maintained equipment, can provide the lowest cost per cut of any of the methods of cutting now in use. But, put that same blade onto a piece of poorly maintained equipment and in the hands of a poorly trained operator and the cost of cutting can virtually put you out of business.
The members of the Saw Manufacturer's Institute have been a significant contributor to the state of the diamond blade art. We hope that some of the knowledge and experience that we have accumulated in our many years in the business can, through this booklet, assist you in keeping your cost down to an absolute minimum.
Of all the problems that confront diamond blade users, blade wear is the most difficult to accurately evaluate. Reporting life performance of identical diamond blade specifications operating under seemingly identical conditions tend to be inconsistent.
Masonry blade operators frequently report blade life in terms of hours, days or weeks. However, these reports neglect to mention type of material being cut, the size of the cuts, and the number of cuts per day. In addition, the amount and the cleanliness of the water and the amount of pressure the operator applies to the cut have an effect on blade life.
Obviously, trying to compare the life of one diamond blade with another, simply on the basis of hours, is analogous to trying to compare a set of tires on one car with an identical set on another car...it is virtually impossible. There are just too many variables...the weight of the car, the types of roads driven on, the condition of the car...particularly the suspension, the manner in which the operator handles the car, etc. Just as many variables apply to diamond blades.
So, the next time you have reason to compare blade life, keep these variables in mind. Some of the problems arising from these variables can be quickly identified, and possibly corrected"...

IMPROPER USE OF A DIAMOND BLADE WITH THE CRACK SAW CAN RESULT IN PROPERTY DAMAGE AND/OR PERSONAL INJURY.
DANGER
PROPER OPERATIONAL USE OF A DIAMOND BLADE THAT DOES NOT MEET INDUSTRY SPECIFICATIONS AND/OR SAFETY STANDARDS WITH THE CRACK SAW CAN RESULT IN PROPERTY DAMAGE AND/OR PERSONAL INJURY.
General Information.
1) " Only mature, properly instructed adults should be permitted to operate machinery and tools.
2) Only utilize the blade to cut the material it is designed and intended to cut. Blades intended for masonry material (stone, concrete bricks, blocks) or blades for steel or ductile iron must only be used in those materials. If you need to cut a material other than the ones listed above, you must use a blade that has been designed for that specific material. Use of a blade in the wrong material may involve a considerable safety risk. It may also reduce the life of the blade or damage the blade.
3) Inspect all diamond blades for damage before use.
4) Never use a new or used diamond blade that shows damage such as cracks, missing segments, damage to the arbor hole or by the flange washers, or other appearances not consistent with the appearance of a new blade. These are indications of previous improper use. If you have any doubt about the safety of a blade, contact the Customer Service Department of the blade manufacturer for assistance. If you do not know the name of the blade manufacturer, contact the Customer Service Department of General Equipment Company for assistance. There is no charge for this service.
5) Always check that the two mounting flanges are of the same diameter and that they are clean and flat. The flanges should not have any cracks or show any abnormal wear. Make sure that the arbor bolt or nut is the correct one for the equipment without damage to the threads. Improper or damaged flange washers and/or damaged fasteners can damage the
blade or cause the blade to come loose from its mount. A blade that comes loose can cause serious bodily injury or death to the operator or bystander. If there are any questions regarding the suitability of a specific mounting flange, contact the Customer Service Department for assistance BEFORE utilizing the diamond blade. There is no charge for this service.
6) Always make sure that the arbor hole in the blade matches the one on the equipment. Do not force the blade onto the spindle. Do not use an arbor shaft (spindle) and blade combination of different sizes. Proper fit is achieved when the blade slides onto the arbor without having more than 0.1 mm (0.005 inch) radial play.
7) Always tighten the bolt or nut for the flange washers in accordance with the equipment manufacturer's specifications.
8) Always make sure that the equipment used is in good operating condition in accordance with the manufacturer's specifications. Do not operate the equipment unless the guards are in good condition, in the proper place and secure. If the equipment appears to be missing any fasteners or has any parts that appear loose or worn, do not operate the equipment until the appropriate repairs are performed. Always make sure the blade you intend to use with the equipment meets all the equipment manufacturer's specifications.
9) Do not operate the equipment with other than the recommended blade sizes. This can result in severe blade damage. Contact the machine manufacturer for advice.
10) Make sure that the spindle speed on the machine does not exceed the maximum RPM indicated on the diamond blade. This can result in blade breakage. Check the blade shaft with a tachometer to verify that the equipment's maximum RPM does not exceed the manufacturer's specifications.
11) Blades designed for wet cutting must be cooled by an adequate, continuous water flow to each side of the blade. Lack of enough coolant will cause excessive heat, poor blade performance and possible segment loss.
12) Blades designed for dry cutting may be used without water coolant. However, dry cutting blades can overheat which will result in loss of blade tension and may ruin the blade. The risk is greatest during long continuous cutting. Most overheating problems can be avoided by lifting the blade out of

ASSEMBLY INSTRUCTIONS/OPERATIONS
the cut and letting it cool by rotating in the air for 15 to 20 seconds after every one minute of cutting.
13) Do not force the tool into the material to be cut. A properly working diamond tool will grind the material without excessive force being applied. If excessive force is needed, it indicates there is damage to the blade to the blade or the wrong blade is being used.
14) Always inspect the diamond blade and the equipment any time you stop during the cut. If you notice any difference in performance as your work progresses, immediately STOP and inspect the equipment and the diamond tool.
15) Do not operate any diamond tool without full knowledge about appropriate cooling of the tool. If a tool is not cooled properly, the blade core can become damaged resulting in the segments coming loose or the blade core (the steel) breaking. This
can result in serious bodily injury or death to the operator or bystander.
16) Do not allow any bystanders in the work area. Never allow anyone to stand in front of a saw that is about to be started or is running.
